MACHINE FOR TRlMMlNGOIL-CAKES.

SPECIFICATION forming part of Letters Patent No. 276,811, dated May 1, .1883.

,Applicationfiled March 2G, 1883. (No model.) i

To all whom it may concern Be it known that I, JoHN T. HARBINE, of Xenia, in the county of Greene and State of Ohio, have invented certain new and useful Improvements in Machines for Trimming Oil- Gakes; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which-- Figure l is a front view of my improved machine for trimming oil-cakes. Fig. 2 is a side view of the cutter-frame, and Fig. 3 is a "erti- V cal section through the same on line 00 m, Fig.

1; and Fig. 4. is a detail view of the cutter.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to machines for trimming the thin rough oily edges of oilcakes, which permits of their more compact packing; and it consists in the improved construction and combination of parts of the same,as hereinafter more fully described and claimed.

In the accompanyingdrawin gs, the letter A indicates an upright frame, formed by four uprights, B, placed in the 'four corners of a rectangle or square, and forming ways G, in which the cutter D slides. This cutter consists of a plate, E, provided with two projecting pins, F, one upon each side, to which the lower ends of a bifurcated pitman, G, are hinged, which reciprocates the cutter. To the vertical sides of this plate E are fastened four blocks or strips, H, two upon each side, front and rear, which slide in the ways formed by the uprights guiding the cutter.

A cutting-blade, l, is fastened to the front side of the plate, projecting below its lower edge, and is adjustably fastened to the same by means of screw-bolts J, passing through vertical slots K in the plate, so that as the cutting-edge is worn by use, and by sharpening it, itmay be adjusted totake up the wear.

Upon the rear side of the plate E is fastened a bent plate, L, the outward-bent portion M of which bears agaiust'and slides upon an. upright plate, N, in the rear of the frame as the cutter is reciprocated, scraping the trimmings of the cakes from said plate. This upright plate N isfaste'ned in the rear of the frame upon a screw, 0, passing through a slotted lip, P, upon the lower end of the plate, into the foundation of the frame, and it may be adjusted closer to or farther from the cutter by moving it in the slotted lip P upon screw 0, thus adjusting the width of the edge trimmed off,the edges of the cakes being brought to bear against the upright plate.

The sides of the frame forming the ways G are provided with four upright plates, Q, fastened to the upright posts and bearing with their inner edges close upon the front and rear surfaces of plate E, leaving narrow slots for the same to slide in, the plates preventingthe trimmings from flying out to the sides.

Two plates, R, are fastened upon the pins F, outside the blocks H, andslide upon the sides of the ways, aiding in guiding the cutter in the same.

The bifurcated pitman G is operated. by a crank, S, fastened upon the drive-shaft '1, so that when the shaft revolves the cutter is reciprocated, trimming in its downstroke the soft imperfectly-pressed edges of the cakes as they are inserted from the front against the upright plate N, the trimmings passing outbelow through a hole, U, in the base of the frame.

The cakes are placed, when being cut, upon the upward-bent edges of a series of plates, V, fastened transversely upon two bars, W, one on each side of an inclined groove, X, in the base of the machine, the upward bent edges of which plates are cut out V-shaped in the center, while the horizontal portions of the plates are bolted or otherwise secured to the bars W. These plates serve to keep the cakes from being pushed out from the cutter, their edges biting into the edge of the cake, and the particles which are abraded from the edges of the cakes by the plates fall into the inclined groove under the same, sliding into a suitable receptacle for the same. If desired, the plates and bars may be cast in one piece, like a grate, the edges of the plates projecting upward from the two bars.

To hold the cakes to be cut, I prefer to use loo a frame, Y, as shown in the drawings, consisting of a side piece and an end piece, set at a sharp angle to each other, the cakes being placed on edge in the frame, and prevented from falling by the oblique end piece, against which the ends of the cakes rest. 7

Having thus described myinvention, Iclailn and desire to secure by Letters Patent of the i United States- 1. The combination, in a machine for trimming oil-cakes, of the cutter D, having adjustable cutter-blade I and bent scraper L, and sliding in ways 0, with the upright plate N, having slotted lip P upon its lower end, sliding adjustably upon screw 0, as and for the purposeshown and set forth. a

2. As an improvementin machines for trimming oil-cakes, the combination and arrangement of the uprights B, plates Q, upright plate N, cutter D, having blade I and scraper L, 2c blocks H, plates It, bifurcated pitman G, crankshaft S T, and cake-holderVW, all constructed to operate as and for the purpose shown and set forth.

In testimony that I claim the foregoing as 25 my own I hate hereunto affixed my signature in presence of two witnesses,

JOHN THOMAS HARBINE.
